WORKING METHOD FOR SYNTHETIC RESIN HARD FOAM BOARD

摘要

PURPOSE:To enhance the working efficiency by abutting a rotating grinding stone on the working object part of a hard foam board being transferred for polishing. CONSTITUTION:A grinding stone 2 which rotates making substantially the turning shaft of the center line is abutted on the working object part of a synthetic resin hard foam board 1 being continuously transferred for polishing. Thus, a shiplap part 4 can efficiently be formed on the end part of the heard foam board 1.
